So far, the company has focused on the older nickel metal hydride technology, which is currently in the Prius. The advanced lithium battery is lighter and more powerful, allowing Toyota to provide more interior space in its hybrids. This works particularly well for cars like the Japanese Estima hybrid that could benefit from a more compact battery, the source added.

Previously, Toyota had said that it would use lithium ion batteries for its electric vehicles and plug-in hybrids.

Toyota’s competitors — Nissan and Honda — both use lithium-ion batteries in their cars, however, Toyota has said that it will stick to using the lithium-ion battery on the Priusbecause hybrids require batteries that rapidly discharge and recharge.


Lithium-Ion Batteries are lighter, more powerful, and less bulky than NiMH batteries, so Toyota’s new Priuses are likely to feature more room and better performance.
